Hi Reuti.
Thank's for your answer, but it seems that i need some time to adapt me 
on the SGE paradigm :-)
So, we had this queues on the PBS system because we have in general 
three types of jobs: The jobs that run rapidly (<2 hours), the jobs that 
need more time (<= 24 hours), and others that run for days o weeks.
The policy is to reserv the more nodes for the rapids jobs. And we 
reserv some nodes for long jobs, like 40% of the cpus.
That's was why we need this three queues with PBS, as we put more 
priority on the rapid queue.
But maybe i'm wrong with SGE, as there should be a better way to satisfy 
this requirements ? Sure i have to investigate more.

Yes, i've just see this man page to have some explanations.

Best Regards.
